What are some common signs of childhood illness in two to three year old babies?

Changes in normal. Changed in normal behavior such as lethargy, poor fluids and food intake, fever, decreased activity or increased sleeping.
Irritability. The ill infant may develop excessive crying, irritability, refuse feedings, or change sleep habits. When their spunk goes away, they prefer to lay still or you get a bad feeling something is up, its worth calling or going in.Diarrhea, cough, or rash may be easy for you to handle at home as long as the kid is taking fluids well & playing some but a call to the nurse can help guide you.
